Welcome to Wednesday, everyone. Typically the middle of the week is slow, and yet we have a plethora of sales for icon packs today, along with a few games that stand out above the crowd. First up is Cessabit, a fantastic spot-the-difference game. Next I have Blackthorn Castle, a popular hidden object game that's currently free. Last but not least is Star Traders: Frontiers, a sci-fi RPG that offers a sea of exploration and customization. As always, I've highlighted all of the interesting titles in bold in order to make discovery easier. So without further ado, here are 24 temporarily free and 51 on-sale apps and games for the middle of the week.
